This invention is the division from application Serial No. 642,767, filed June 1, 1923, and relates toa projector for motion pictures.

.An object of the present invention is to provide a motion picture projector in which the film is uniformly movable, during the projection of pictures at all points throughout drums or spools and which has the projecting mechanism including movable portions adapted to intermittently'project the picture squares on the film. Another object of the invention resides in providing a motion picture projector having mechanism for mounting and uniformly moving afilm strip therein, and a projecting mechanism for'intermittently projecting the pictures from the moving film including a movable light controlling and rojecting mechanism intermittently movable with said film for projecting picture squares thereon. A further object of the invention resides in providing a picture projection mechanism for projecting two series of pictures beginning at opposite ends of the same strip with the pictures of each series arranged in alternate relation, in which the projecting mechanism is provided with suitable means for adjusting the scope of movement of a light controlling mechanism intermittently movable with a uniformly moving film having said pictures thereon in order to project the successive pictures of each picture series intermittently onto a suitable screen. i The invention further comprehends the provision of a substantially simple projector for mounting and uniformly moving a film from one spool to another, and for adjustably controlling the light projecting mechanism for intermittent movement with the uniformly moving film, to intermittently project the picture squares from the filin. In addition, the invention comprehends 1mcarrying out the above and other objects which are more particularly pointed out in the following detailed description and in the claims directed to a preferred form of the invention, it being understood, however, that various changes in the size, construction, and

arrangement and operation of the parts may be made for projecting the pictures on the same principle of operation as the present machine withoutdeparting from the spirit or scope of the invention as set forth herein.

tuting my invention. If desirable, this casing 5 may be equipped with a suitable form of lid, the same, however, being not at all materlal, and therefore notshown. With particular reference to the picture projecting mechanism, the same includes an open base plate 6 of suitable material form which is suspended an electric motor 7, the armature shaft of which is equipped with a speed governor 8 as well as .a brake plate 9, that cooperates with a speed regulating mechanism designated generally 10, the samebeing 0 conventional design and therefore not specifically described.

The end of the armature shaft of said motor is equipped with a worm 11 which is intermeshed with a complementary gear upon the end of a vertical shaft 12 that is. suitably journaled through the said base plate 6 as well as an under structure 13. This shaft 12 'is substantiall intermediate the front and rear ends of t e base plate 6 and adjacent one side thereof, the same being equipped with a fly wheel 14 as well'as a belt pulley 15.

Rearwardly of this tially intermediate the plate 6 is a vertical shaft 16, the lower end of which is equipped with belt pulley 17 of less circumference than that of the pulley v15 upon the shaft 12.- The pulleys 15 and 17 are in substantial alignment with each other, and are operatively connected by a relatively loose spiral spring belt 18, which will permit of a slippage of the shaft 16 with respect to the shaft 12 for purposes presently to be set forth. I

superposed upon the base plate 6 and maintained in position thereon in any manner desirable is a substantially rectangular shaped frame that embodies a front wall 19,

rear wall 20, side walls 21 and 22, respectively, and a cover plate 23. It being noticed from a consideration of Figure 3 that the side wall 22 of the frame is of lesser height than the other walls for purposes to be presently set forth. The front and rear walls 19 and 20 of said frame are provided'upon' their in-' for assisting the guiding of the film carrier into the frame, the said side wall 22 of the frame is provided adjacent its opposite ends with outwardly extending rest plates 24 that are in alignment with the said guide flanges of the frame and are adapted for receiving the front end of the film carrier preliminary to the insertion of the same within the frame.

The front and rear walls '19 and 20 of this frame are provided with a row of spaced and circular shaped openings 25 as more clearly shown in Figure 1', these openings being provided for considerably lessening the weight of the machine as well as for providing heat outlets, the opening in the front wall 19 adfor the purpose of permitting the projection of the lightrays from the source of illuminaf tion that have passed through the picture.

The side wall 21 of the said frame is provided adjacent the front wall 19 with a, relatively elongated light opening 26 and-slid--- ably disposed upon a pair of guide bars 27 that are suitably anchored upon the said base plate 6 and directly rearwardly ofthe light opening 26 in the said side wall 21 of the frame is what I hereinafter term a carriage 28. This carriage comprises as more clearly shown in Figure'9, a vertically directed plate 29 that is formed. at its upper end with an opening 30 of substantial square shape, this opening being in direct alignment with the said light opening 26 of the side wall 21 of the frame. Surrounding this opening 30 and secured in any manner desirable to the said plate 29 is an inwardly extending light hood 31, that has its inner end formed with upper and lower fingers 32 between which is slidable the film designated in Figure 3, 33. The walls of this hood converge inwardly and the inner end of the same is of dimensions substantially equivalent to the dimensions of the picture square of the picture film. The said carriage designated generally 28 also comprises a pair of spaced lenses 34, Figure 9, that are disposed beneath the said opening 30 in the plate 29 and an inclined mirror 35, which is in direct longitudinal alignment with the said lenses 34.

Immediately rearwardly of the said carriage 28 is a prism 36 of a length substantially equivalent or slightly greater than the light opening 26 in the wall 21 of the frame,

whereby as the light projects through said opening through a source of illumination to be hereinafter described and after the same has passed through the film 33, the same will be projected downwardly onto the mirror 35 and thence through the lenses 34 out through the said opening 25 of the wall 19 of the frame onto a suitable screen. I Now, having particular reference to th combinedpicture andsound film 33'as per Figures 13 and 14, the same is of the usual celluloid material having a gelatine coating 2 upon one side thereof. In the present innoted spaced from each with projecting pins stance, this film includes two different picture series, the picture square of one series occupying each alternate picture square of the film, while the pictures of the other series occupy the remaining alternate squares of the fihn. One of these picture series is degenerally 34', while the other picture series is denoted generally 35, and for more accurately disclosing the exact nature of this film, the squares of the picture series 34 is marked with the numerals 1 to 7 while the picture squares of the other series is marked with the letters a to g. The picture series 34 begins at one end of the film, while the picture squares of the remaining-series begins at the opposite end of the film, and as clearly shownin Figure 13,the picture squares of each seriesarearrangedinup-side-down'relation to eachother. Upontheuncoatedsideofthefilm and adjacent one of the edges thereof is a. sound groove 36, the sound waves of which are representative of the picture series 34. It is to be understood that these sound waves .are recorded simultaneously with the taking of thesaid picture series34 for thereby providing an absolute synchronization therebetween. Upon the opposite edge of said film 33 is a similar sound groove 37, the waves of which are representative of the picture series 35., tnesewaves being also recorded simultaneously with the taking of the picture series 35'. The c ter of the film 33 is formed with elongated openings 38 that are arranged between each alternate pair of pic ture squares, the same adapted for receiving the pins of a film drive element hereinafter to be described.

In Figures 10 and 11 there is shown a par- .ticular type of film box that is to be used in conjunction with m machine, this box designated 39 being of fiiit rectangular shape and embodying a top wall 40, bottom wall 41 and integral front, rear and side walls 42, 43, and 44 respectively." The top wall 40 is removable for obvious purposesand loosely journaled between the top and bottom walls and other are a pair of film rollers 45,. These rollers are each keyed upon shafts 46-.46, the ends of the shafts projecting through the said top and bottom walls of the film box 39. The opposite ends of said shafts are equipped with cross plates 47 and rollers 48, respectively. The cross plate and roller of one shaft beingarrangedat the opposite side of the film box 39 with respect to the cross plate and roller of the other shaft. Adjacent the front wall 42 of the box 39 and walls thereof is a roller 49 that is equipped 50 that engage through the openings 38 of the film 33, when the same is'properly positioned within the box. This roller is also upon a shaft 51, the opposite ends of which project outwardly through 57 and 58' substantially intermediate the end the box and are equipped with cross plates 52. In actual practice, one end of the film 33 is secured in the usual manner to one of the rollers 45, this fihn being extended forwardly within the box and over a corner roller 53, and thence positioned over the said roller 49 and maintained in tight. engagement therewith by other rollers 54 upon opposite sides of the roller 49. The film box also carries a further roller 55 adjacent the opposite front corner thereof, and over which the film is trained, the same being then directed rearwardly and secured to the remaining roller 45,

This film box 39 is equipped with a handle 56 and is adapted to be slidably positioned within the frame that 19, 20, 21 and 22, the position of this box within the frame being more clearly shown in Figure 3. .The top wall 40 of the box is provided at its front side and adjacent one side of the film roller 49 with a light opening 57, while the bottom of wall 41 of the box is pro vided adjacent the opposite side of the roller 49 with a similar light opening 58, the front wall 42 of the box being provided forwardly of eachlight opening 57 and 58 with openings respectively. These openings are adapted, at" different positions of the box within the frame, to aline with the light opening 26 in the wall 21 of the frame for obvious purposes.

Splined upon the upper ends of the before mentioned shafts12 and 16 are wheels 59 and 60 respectively.- Each of these wheels being provided with a vertically projecting annular row of spaced pins 59 and 60' respectively. Each of these wheels is circumferentially grooved as more clearly shown in Figure-5 and in engagement with the groove of the wheel 59 are inwardly directed pins thatis made up of the walls are carried by the yoked end of a lever 61,

this lever being pivoted at 62 to a standard 63 that is carried by or formed integrally with the base plate 6. The opposite end of this lever 61 is formed with a pendent leg 64 for purposes hereinafter described, and as a means for normally holding the'said wheels 59 in a position downwardly upon its shaft, as shown in Figure 5, there is provided a coiled spring 65 secured at one end to the lever and at its opposite end to the base plate 6.

Similarly engaged with the groove in the wheel 60 are inwardly directed pins upon the yoked end of a lever 66, this lever being also similarly pivotally secured to a post 67 and formed at its inner end with a pendent leg 68. In this instance, this pendent leg 68 is equipped with a pair of projecting pins 69 between which engage one end of an arm 70 that extends laterally and is secured in any manner desirable to a rectilinearly movable bar 71 movablewithin standards 72. The front end of this bar has close contact with the pendent leg 64 of the lever 61, the

by a curved projection 73 upon the lower end of a fiat like lever 7 4 that is pivotally secured to an open rectangular shaped metallic plate 7 5 that is supported a slight distance above the base plate 6. a

Similarly engaged with the groove in the wheel 60 are inwardly directed pins upon the yoked end of a lever 66, this lever being also similarly pivotally secured to a post 67 and formed at its'inner end with a pendent leg 68'. In this instance, this pendent leg 68 is equipped with a pair of projecting pins 69 between whiehengage one end of an arm 7 O that extends laterally and is secured in any manner desirable to a rectilinearly movable bar 71 movable within standards 72. The

front end of this bar has close contact with the pen dent leg 64 of the lever 61, the opposite end thereof adapted to be engaged by a curved projection 73 upon the lower end of a flat like lever 74 that is pivotally secured to an open rectangular shaped metallic plate 75 that is supported a slight distance above the base plate 6.

In view of the foregoing, it will be obvious that when this flat like lever 7 4. is in adownwardly swung position as per Figure 4, the wheels 59 and ,60-.upon the shafts 12 and 16', respectively, will be in a position downwardly thereon'due to the influence of the springs. It is to be understood that a spring, similar in all respects to the spring 65 is secured between the base plate 6 and the lever 66. When these wheels are in their downward position and the cover 23 of the before described frame is removed, the film box 39 may be slid within the frame, and after the same has been positioned therein, the cover 23 is applied, and the lever 7 at swung upwardly to the position of Figure 3. This movement of the lever so effects the arm 70 and rod 71 as to raise the wheels 59 and 60 upon their respective shafts and consequently position the vertically directed pins 59' and 60 in engagement with the adjacent plate 52 of the shaft 51 of the film roller 50 and the plate 4701f the adjacent shaft 46 of the respective roller 45 whereby when the motor 7 is started, the rotation of these wheels 59 and 60 will cause a consequent unwinding of the film from one .roller 45 to the opposite roller 45.

As a means for maintaining this lever 7 4 in the position shown in Figure 3, the frame cover 23 is provided with at lip 76 that is adapted to .be engaged by a dog 77 carried by the lever 7 8 pivoted at 79 adjacent the upper end of the flat like lever 74.

Again, having reference to the prism 36, and as more clearly shown in Figure 15, the same is disposed or formed integral with the forward upwardly projecting ends 80 of a pair of rearwardly directed flat like bars 81. The opposite ends of these bars are secured to a cross rod 82 that is disposed for rocking movement in a pair of spaced'standards 83 formed vertically upon the said base plate 6. As more clearly shown in Figure 3, the inner end of this rod 82 is formed with a pendent leg 84 that is in contact with a laterally directed pin 85' upon the said sliding rod 71, whereby after the film box 39 has been positioned and the fiat like lever swung upwardly, a forward movement of said rod 71 will naturally cause a rocking movement of the rod 82, for thereby extending the prism 36 upwardly into the respective opening of either the top or bottom wall 40 or 41 of the said film box.

Secured to a post 86 that is upon the base plate 6 at a point adjacent the front wall 19 of the film box frame is a flat like curved spring 87 that is so positioned as to engage the adjacent roller 48 of its respective film /roller shaft 46 when the box is slid forwardly within the frame, this spring thereby effecting a brake for the said respective film roller shaft for ,preventing the free unwinding of the film from its respective roller. This spring further functions as a means for projecting the film box 39 aslight distance outwardly of the frame when the lever 74 has been swung downwardly.

The carriage 28 has rectilinear movement upon the bars 27, and it might be well to herein note that during the projection of one picture series 'of the fihn 33, the carriage moves in a certain horizontal zone to permit the projection of but one picture series, while during the projection of the other picture series, the said carriage moves in a different horizontal zone. This is necessary for the proper projection of the pictures and as this carriage moves in a direction similar to the direction of movement of the film, the opening 30 of the plate 29 of the carriage will be in a position forwardly of one of the picture squares of that particular series for permitting the light rays to project through that After the carriage has.

particular square. moved a certain distance 1n a direction similar to the direction of movement-of the picture film, the same is released, and then snapped forwardly, whereby the opening ofthe said plate is positioned forwardly of the next picture square of that particular series, whereby the light passes therethrough and projects the picture, and so on until all of the picture squares of that particular series have been projected. It is therefore absolutely necessary that the said carriage move in different'horizontal zones during the projection of the different picture series upon the film, and the mechanism for controlling the rectilinear movement of the carriage is as follows Disposed upon the base plate 6 and secured thereto in any manner desirable and surrounding the shaft 12 is a circular strip of metal 88 that is formed with a cut-out portion as more clearly shown in Figure 6. The

underside of this metallic strip is mortised at its inner end for receiving the flange 89 of a disk 90 that has free rotary movement in opposite directions around the'shaft 12. This disc-is formed with a central vertically projecting sleeve 91 that surrounds said shaft 12, and has loosely positioned thereon a halfmoon shaped plate 92. Pivotally secured to this plate 92 as at 93 is a somewhat arcuate shaped lever 94, a portion of which is maintained in normally close contact with the said sleeve 91 of the disk 90, through the medium of a band spring 95. The inner side of this lever- 94 is formed with a hook shaped cut out 96, that is adapted to receive successively, pendent spaced ins 97, of a collar 98, keyed to the shaft 12 beneath the before described splined member 59, as the shaft 12 is being rotated under the influence of the motor 7. Connected at one end to the half-moon shaped plate 92 and at its 0 posite end to the said carriage 28 is a flexi le steel band 99, that is adapted to be wound onto the plate 92, as the same rotates in one direction. As a means for normally maintaining the carriage 28 in the position of Figure 4, there'is provided a hand spring 100 secured at one end to the before mentioned post that carries the spring 87 and that engages at its opposite end a convenient point of the carriage. The disk 90 is formed with a laterally extending arm 101, to which is pivotally secured one end of a connecting rod 102, the opposite end of this rod being pivotally secured to one arm of a bell crank 103. This bell crank is suitably pivotally secured to the base plate 6, and is provided upon its opposite arm with an upwardly extending actuating knob 104 that is slidable within an-arcuate slot 105 in the before mentioned plate member 75. From a consideration of'Fig'ure 6, it will be at once apparent that the arm 101 of the disk 90 has movement between the opposite ends of the metallic strip 88.

It is preferable thatthe opposite ends of this arcuate slot 105 be marked with the characters 1 and 2 as per Figure 2, and that the opposite sides of the film box 39 be also similarly marked whereby the said knob may be thrown to different positions for permitting the carriage to move in different horizontal zones during the projection of the different picture series upon the film strip 33. For permitting the marking on the film box 39 to be viewed, the cover plate 23 of the before described frame is formed with a central opening 23, Figure 2.

For effecting the movement of the half moon shaped plate 92 in one direction when the disk 90 is moved in a similar direction, there is provided a curved spring 106 that is secured atone end to a post 107 upon the said disk 90, the opposite end of this spring contacting with the adjacent end of the said plate 92. This spring 106 also serves as a flexible stop for the plate 92 as the same is rotated in a reverse direction, under the influence of the carriage controlled spring 100.

Assuming that the film box 39 has been positioned in its frame in such a manner as to project one of the picture series, this picture series being indicated on the film box 2, Figure 2. It is therefore necessary that the before mentioned knob 104 be swung to the position in this figure, which will rotate the disk 90 around the shaft to the position of Figure 6 for consequently sliding the carriage 28 slightly rearwardly upon the bars 27 for permitting the same to move in opposite directions in a certain horizontal zone for permitting of the projection only of the picture squares of that particular picture series. After the film box has been positioned and the lid 23 of the frame applied, and the lever 74 swung upwardly as per Figures 1 and 2, the pins 59 of the wheels 59 and the pins 69' of the wheel 60 will engage the plates 52 and 46 of the respective roller shafts 51 and 46. Upon the starting of the motor 7, which is of course, in circuit with a suitable source of supply, this circuit adapted to be closed by a lever 108 of a desirable form of switch, the shafts 12 and 16 will be rotated. In view of the forwardly projecting pins 50 upon the wheel .49 projecting through the openings 38 in the film 33, this film will unwound from one of the rollers 45 and be consequently wound upon the opposite roller 45. In view of the forwardly projecting pins 50 upon the wheel 49 projecting through the be effectively be effectively unwound from one of the rollers 45 and be consequently wound upon the opposite ro1ler'45, the connection between the shafts 12 and 16 permitting of a slippage of the latter mentioned shaft with respect to the first mentioned shaft as the film becomes wound upon the said roller 45 for obvious purposes. Upon the positioning of the film box 39, the opening of the plate 29 will be directly forwardly of the first picture square of the particular picture series to be projected, and naturally-as the shaft 12 rotates, a certain one of the pins 97 will engage the edge of the notch 96 in the arcuate shit (1 lever 94, and cause a rotation of the half-moon shaped plate 92. A movement of this plate 92 will occasion a movement of the carriage 28 in the direction of movement of the film and after this carriage 28 has been moved a certain distance inwardly, this arcuate lever 94 will engage a vertically projecting pm 109 upon the disk 90 for releasing the said lever from the pin, which will thereby fiuence of the spring 100 until the notch of the lever 94 receives another pin, it being understood that the reverse movement of the carriage is of a distance equivalent to the dispermit the carriage to snap forwardly under the in-" tance apart of the picture squares of the re- -knob 104 is moved to an opposite position within the arcuate slot 105 for thereby permitj ner to the t ting the movement of the carriage 28 in a different horizontal zone, whereby the plate 29 of this carriage will accompany the movement of the respective picture squares of that picture seriesv across the light opening 26 in the side wall 21 of the frame. Y Directly forwardly of the film roller 49, the front wall 42 of the film box 39 is provided with an opening 109, into which extends the stylus 110 of a'sound box 111. As more clearly shown in Figure 10, this stylus has close contact with the sound groove upon the film 33 that is at the upper edge of the film during the projection of that particular picture series, it being noted that this stylus is at a substantial angle to the longitudinal axis of the film for obvious purposes. This stylus 110 is maintained in engagement with the sound groove of the film through the medium of a spring 110.

The sound box 111 is carried upon the upper end of a hollow tone arm 112, that is loosely positioned within a sleeve 113 that is received within an opening in the base plate 6, and terminates at its upper end in a flange 114. In this instance, it is necessary that the open frame plate7 5 be provided with an opening in alinement with said sleeve 113 for permitting of the passage of the tone "arm therethrough, as more clearly shown in Figure 3. Connected t its upper end in a suitable manbne arm112 is a rod 115 that is slidable through a cross guide 116 formed within the lower end ofsaid sleeve 113. -In position beneath the lower end of-this rod 115 is a wedge-shaped plate 117 that is formed upon one end of one arm 118 of a bell crank 119, Figure 12. This bell crank is pivotally secured beneath the sleeve 113, and its other arm 120 extends beneath thesbase plate for a portion of its length, and is then bent upwardly and outwardly to provide an extension 121 that projects up through the base plate 6, and engages through an opening in the wall 22 of the film box frame, this end being provided with a point 122 and an operating knob 123. The open shaped frame plate 75 is provided with graduations 124 that are adjacent said pointer. 122, and it will be at once apparent that by swinging the bell crank upon its pivot, the wedge shaped plate 117 will be moved inwardly and outwardly beneath the lower end of the rod 115, whereby the stylus 110 of the sound box'lll may be properly guided into the respective sound groove of the picture strip 33 as the proper series is being projected] As shown by the dotted lines in Figure 1, the tone arm 112 may be, and preferably is, in communication with atone arm extension 125 that has its opposite end positioned within an opening 126 in the front wall of the casing 5, this opening adapted to, in turn, receive a phonographic horn of desirable form and size.

- Detachably secured to one side of the casing 5 is a laterally projecting supporting arm 127 that carries at its outer end a lamp bulb socket 128 and positioned within this socket is preferably a stereopticon bulb 129 that is disposed within a sectional metallic globe 130, this globe being provided internally with a reflector 131 immediately behind the said bulb 129. The inner side of the globe 130 is provided with a light opening in commnnication with which is a hood 132 that carries a of a beam of light, across which is movable a picture strip,- having a uniform and continuous movement, said means being adapted tocontrol the projection of the lightand the rectification thereof, in order to intermittently project a redetermined series of pictures on said mova le strip, in succession, onto a suitable screen, for producing a moving picture. Simultaneously with the intermittent projection of a predetermined series of pictures from said strip, a suitable sound reproducing means, above described, synchronously reproduces sound recorded on said continuously movable strip, incident to the pictures being projected therefrom. This construction forms an important feature of the machine, in order that the projection of pictures and reproduction of sound can be accurately an synchronously reproduced. I Another important feature of the invention resides in the reversible film carrier or box 1 which is reversible in the projecting machine, so that a film having a series of pictures arranged in alternate relation and starting from opposite ends of the film may be projected by tural elements, it is nevertheless to be understood that in the future practice of the device, departures may be had therefrom without affecting the spirit and scope of the appended claims.
